4x4 Suspension Basics - spring Over Axle Suspension - Photo 35383710

Spring-over axle (SOA) suspension setups have become very popular. With this arrangement suspension articulation is increased due to the additional leverage on the springs. SOA setups also create more ground clearance under the axle by moving the leaf spring and perch to the top of the axle tube. This isn't an easy conversion but it works very well. The conversion requires a good deal of cutting and welding and achieving the correct result can take time and patience. Many aftermarket SOAS kits area available to take some of the guess work out of it.
